WILLIAM S. ROBERTSON, OF BARBERTON, OHIO, ASSIGNOR OF ONE-HALF TO HUGHES, OF CLEVELAND, OHIO.

GATE FOR LIQUID-RECEPTACLES.

To all whom it may concern:

Be it known that I, WILLIAM S. ROBERTSON, a citizen of the United States, and a resident of Barberton, county oi Summit, and State of Ohio, have invented a new and useful Improvement in Gates for Liquid- Receptacles, of which the following is a specification, the principle of the invention being herein explained and the best mode in which l have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to a gate for varnish or similar liquid receptacles and has for its object the production of a gate which shall be simple, easily operable and effective. i

Said invention consists of means hereinafter fully described and specifically set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawingz-Figure 1 represents a front elevation of my improved gate attached to a varnish or similar receptacle, the open position of the operating handle being also shown in dotted lines; Fig. 2 represents a central vertical section, taken upon the plane indicated by the line 2-2, Fig. l; Fig. 3 represents a central horizontal section, taken upon the plane indicated by line 3 3, Fig. l; Fig. 4 represents a perspective view of a cap adapted to iit snugly over a port registering with the outlet of the receptacle and provided with a small centrally located shoulder by reason of which, as hereinafter fully explained, it has a limited rocking or tilting movement; and Fig. 5 represents a perspective view of an operating lever or handle.

My improved gate will find most ready use upon barrels, kegs and other receptacles which are adapted to retain molasses, paint, varnish, etc., and from which it is frequently desired to draw oi'f certain quantities. My invention is designed to enable this to be done conveniently and without leakage of the liquid. Said invention com-prises a plate or a body portion A provided with a central annular hollow boss a which has an internal screw-thread, whereby it is adapted to be secured to a conduit B or any othersuitable outlet from the liquid receptacle. I prefer this method of attaching the gate to the receptacle, although, obviously, any other suitable connection may be employed which will provide suitable registering ports in the gate and the receptacle outlet.

When the gate is closed, the port b of the conduit B is covered by a small cap C which is of a size and contour to enable it to t snugly up against the outer pe- Specification of Letters Patent.

riphery of the boss a. The cap C is held in such position by means of anoperating handle or lever D which is provided with a shallow seat d Within which the cap C is partially confined, and thus restrained from sliding laterally and being displaced from off the boss a.

The handle D is of a contour which enables it to be fitted over the boss a and still allow it to lie iiat against the main part a of the plate A upon both sides of said boss a, as clearly shown in Fig. 3. Said handle D is provided with a passage-way df for a small pin a2 xed in the plate A, said passage-way forming a bearing for said pin, thus pivoting the handle D at one end. The pivotal movement'of the handle D is limited in both directions, in one direction by a lug or stop-pin a3 against which the handle abuts when the gate is opened to allow liquid to escape, as shown in dotted lines in Fig. l, said pin a3 being so positioned that the handle engages same just before the cap O has been carried entirely over and off the boss a, thus preventing the cap O from falling out of the retaining seat d. In the other direction the handle D is allowed pivotal movement only to the extentof enabling it to carry the cap O completely over the port b, it then being prevented from further movement by means of a lug or clip E, screwed to the plate A by a screw c2 and having secured to it an angular off-set or arm e under which the lever passes and which is adapted to engage the latter tightly from the top when the lug E is screwed down tightly to the plate A. In the construction shown, the lug E and arm e are one integral piece. A similar lug E, screw e3 and arm e are used to retain the lever D upon the pin a2, as shown in Fig. 1l Slightly loosening up the screw e2 will enable the handle D to be moved to open or close the gate, as will be readily understood.

Slightly loosening up the screw e3 will enable the 111g E/ and arm e to be swung around upon such screw e3 as an axis, and allow the handle D to be taken off from or replaced upon the pin a2. It will be noted from Fig. 4 that the cap C is provided with a small centrally located cylindrical teat c which is adapted to lie within a shallow socket d2 cut within the portion d of the handle D, that serves as a seat for the cap C, the socket d2 being somewhat less in depth than the thickness of the. teat c, as will be noted from Figs. 2 and 3, whereby said cap C has a slight rocking or tilting movement within the seat d. By means of this construction, the handle D is enabled to slide easily under thearm e when closing the gate, but is engaged by such arm tightly, when the gate is completely closed and the cap lies equally lush with all parts of the boss a. This effect is due to the fact that, when the gate is closed, the cap O engages all parts ofthe boss a with equal pressure, and hence cannot be tilted or rocked, and so presses the handle D tightly up against the arm e; Whereas, when the cap C is partially displaced from the boss a, it is tilted to some extent, due to the unequal pressure ot' said cap upon diierent portions of said boss and thus the handle D drops away a tril'le from the arm e and has a freer movement thereunder.

Other modes of applying the principle of my invention may be employed instead oi the one explained, change being made as regards the means herein disclosed, provided the means stated by any one oi the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention z- A l. In a gate for liquid receptacles, the combination of a body-portion adapted to be connected to the receptacle vand provided with an outlet for the receptacles contents;

a pin secured to said body-portion at one side of said out4 let; a handle pivoted at one end to said pin; means movably mounted upon said body-portion and adapted to retain such end of said handle upon said pin; and a cap borne by said handle and adapted to close said outlet.

2. In a gate tor liquid receptacles, the combination of a body-portion adapted to be connected to the receptacle and provided with an outlet for the receptacles contents; a

`pin secured to said body-portion at one side of said outlet;

a handle pivotcd at one end to said pin; a clip movably mounted upon said body-portion and provided with an angular offset adapted in one position of said clip to retain such end of said handle upon said pin; and a cap borne by said handle and adapted to close said outlet.

3. In a gate for liquid receptacles, the combination of a body portion adapted to be connected to the receptacle and provided with au apertured boss adapted to register with said receptacles outlet; a pin secured to `said body portion at one side ol said boss; a handle pivoted at oneI end on said pin and conforming to the shape ot' said boss so as to be movable transversely across the saine: a clip inovably mounted on said body portion and adapted normally to retain such end of said handle upon said pin; a separate cap borne by said handle and adapted to close the aperA ture in said boss; and a second clip adapted to engage said handle when disposed across said boss so as to seat, said cap tightly upon the latter.

L In a gate for liquid receptacles, the combination ot' a body portion adapted to be connected to the receptacle and provided with a hollow boss adapted to register with the receptacle outlet.; a pin secured to said body portion. an operating handle pivoted at one end to said pin und movable transversely of said boss; stop-lues secured to said body portion and adapted to contact: with said handle to limit the movement oi the latter; a cap located interniediately of said handle and said boss and adapted to close the outlet: of the latter; a scat in said handle for said cap; a cylindrical teat upon said cap and a socket, of less depth than the thickness of the teat, in said seat.- portion ot said cap for receiving said teat", said stop-lues being arranged to allow the movement ol' said handle only upon one side of said boss, and on that sido only to the extreme engaging position of said cap and said boss; and said cap arranged, by the construction ot said teat, and socket, to assullle a tilted position except when it. conipletely covers said boss opening.

Signed by me, this 19th day of May 1905.
